18.  Your shepherds are sleeping, O king of Assyria; your nobles are lying down.  Your people are scattered on the mountains and there is no one to regather them. 
19.  There is no relief for your breakdown, your wound is incurable.  All who hear about you clap their hands over you, for on whom has not your evil passed continually?

In about 612 B.C., Nineveh was destroyed.

Here, at the end of Nahum, God reminds the Ninevites that time is short.  God tells them that they are scattered and nobody is coming to their rescue.  These seem like harsh words, unless you have read Jonah and the earlier words of Nahum.

Nahum tells us that the people of Assyria have more than forsaken God - they have trampled righteousness. 

God will not stand for it!

Verse 19 contains frightening words:  "Your wound is incurable."

Perhaps we will not push God to such extremes.
